fence_compute - Man Page
Fence agent for the automatic resurrection of OpenStack compute instances
Description
Used to tell Nova that compute nodes are down and to reschedule flagged instances
The fence agent accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. The agent can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
